Hallo Karl und Uli,
I suspect, to really do a good job of gamut mapping, you would not want to
have a "global" approach but a "selective", "local" approach? If 100 means
all farben kompressed, surely all colors could not be compressed the *same*?
Or uniformly? Across all hue angles?
I am refering to the typical RGB gamut shape where the blue has a large
chroma and, in my mind, would require a differential compression than, say,
the reds or greens? Because those have typical less chroma? So therefore,
the rate of compression would have to be adjusted according to the hue
angle?
